To solve this issue of mine, I've done something not very elegant: I've written 5.427 commands with all the files to merge and just made an executable file with all the commands copy pasted there. This is how it looks like (for the first 11 files):

Code:
./match.pl  -f 9464294024_R01C01header -g 9466656017_R01C01header -k 1 -l 1 -v "5 6 7" > ./result/1
./match.pl  -f 9464294024_R01C02header -g ./result/1 -k 1 -l 1 -v "5 6 7" > ./result/2
./match.pl  -f 9464294024_R02C01header -g ./result/2 -k 1 -l 1 -v "5 6 7" > ./result/3
./match.pl  -f 9464294024_R02C02header -g ./result/3 -k 1 -l 1 -v "5 6 7" > ./result/4
./match.pl  -f 9464294024_R03C01header -g ./result/4 -k 1 -l 1 -v "5 6 7" > ./result/5
./match.pl  -f 9464294024_R03C02header -g ./result/5 -k 1 -l 1 -v "5 6 7" > ./result/6
./match.pl  -f 9464294024_R04C01header -g ./result/6 -k 1 -l 1 -v "5 6 7" > ./result/7
./match.pl  -f 9464294024_R04C02header -g ./result/7 -k 1 -l 1 -v "5 6 7" > ./result/8
./match.pl  -f 9464294024_R05C01header -g ./result/8 -k 1 -l 1 -v "5 6 7" > ./result/9
./match.pl  -f 9464294024_R05C02header -g ./result/9 -k 1 -l 1 -v "5 6 7" > ./result/10

I've used numbers to name the output files as it was easier to loop them for writing. The commands work without any problem. And I've got my output.

I must admit that I do not understand the script you've provided, nor the diagnostics (I'm a beginner, posting in the forum for beginners) and, thus, cannot comment on your statement of your script working or what the diagnostics say. I'm grateful for your time and help, but am a bit baffled as to why the general consensus is that the only possible explanations to this situation are in two possibilities (1) my perl script having a problem or (2) I'm not providing truthful/good information.
